The idea that a person’s virtue might reside in their blood was a medieval one that justified systems of familial succession.

The pentangle Gawain has painted on the front of his shield represents his characteristics in five areas, as the following lines go on to detail: the perfection of his five senses, the dexterity of his five fingers, his devotion to the five wounds of Christ, his focus on the five joys Mary had in Christ, and his devotion to five virtues.
